Hello, OP here. We didn’t yet have access to a proper critical commentary and did our best with the image captions, although our best was a rather poor job in this case — much trickier than anticipated. I went to the Berlin Staatsbibliothek today for research and new captions will go live tomorrow. (Although even the experts are confused as to what the “Jerusalem artichoke” image is supposed to be — they suggest watermelon or cucumber.)
